The transition towards winter becomes evident in November
, with a decrease in daylight and sunshine hours. The sea temperature cools down to 28°C, yet remains warm enough for water activities. Subtle shifts in humidity and UV index indicate the onset of the cooler, drier season. Contrastingly, November experiences a substantial amount of rainfall, with a total of 123mm precipitation.
The average high-temperature in Cozumel
during November registers at a moderately hot 29.7°C, maintaining a close resemblance to the previous month. November witnesses an average low-temperature hovering around a pleasant 21.7°C.
In November, the heat index is evaluated at a fiery hot 38°C. Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.Note
: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Without adequate protection, skin and eyes might suffer damage. Ensure precautions are in place. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Alert! Sand and water increase UV exposure due to their reflective properties.
